OP27EJG

低噪声高速精密运算放大器 LOW-NOISE HIGH-SPEED PRECISION OPERATIONAL AMPLIFIERS

description

The OP27 and OP37 operational amplifiers combine outstanding noise performance with

excellent precision and high-speed specifications. The wideband noise is only 3 nV/√Hzand with the 1/f noise corner at 2.7 Hz, low noise is maintained for all low-frequency applications.

The outstanding characteristics of the OP27 and OP37 make these devices excellent choices for low-noise amplifier applications requiring precision performance and reliability. Additionally,

the OP37 is free of latch-up in high-gain, large-capacitive-feedback configurations.
